Design standard accd to API 609, ASME B16.34.The butterfly plate rotates from 0° to 8°-12°, the butterfly plate sealing face will break away from the valve seat sealing face completely, thus reducing the mechanical abrasion and the extrusion corner travel during opening or closing the Butterfly Valve. With the reduction of mechanical abrasion and extrusion, the sealing performance and service life of the butterfly valve will be improved greatly.
